Huanglongmon

⇨ JapaneseSupervising the "Four Holy Beasts" who protect the east, west, south, and north of the Digital World, it is an emperor Digimon who is enshrined in the center and rules the "world". Due to the angel Digimon that descended in the distant past, it was sealed in the deepest, darkest place within the earth. The Four Holy Beasts lost their rule because of this, causing a struggle for hegemony, but an equilibrium is maintained at present. This being is good but also evil, and is called the "Taiji" of light and darkness. It has eight eyes and twelve external Digicores, and its gigantic body is covered in scales of the special "Huanglong Ore" that boasts of absolute hardness, so inflicting even a single wound upon it is impossible. Its Special Moves are continuously disassembling everything in the Digital World, throughout eternity, into the two extremes of light and darkness, driving it into non-existence before long (Taikyoku), and generating a gigantic typhoon of an earthflow on the scale of a natural disaster (Oukai).

Huanglong Ore

As the ore from which "Chrondigizoit Metal" is derived, it is a virtual ore that boasts of absolute hardness. Only Huanglong Ore is able to actually scratch Huanglong Ore, and because it cannot be compared with other minerals and metals, it is impossible to measure its hardness. Despite this extreme hardness, its weight is extremely great, so it is not suitable for things like weapons or armor. Its scarcity is also great, so it can only be found deep underground. Also, it is said that it requires many, many years, more than those since the age of myth, in order to unify Huanglong Ore with living things, and at present there have been not been any Digimon discovered to have unified with this super-hard ore other than Huanglongmon. Chrondigizoit Metal resolves these weaknesses, and is said to be a more excellent rare metal.

Although not appearing directly, Gennai tries to ask him and the other Holy Beasts to help the Chosen Children in Odaiba. They can not help but give their sacred power to the children's Digimon, who take roles from each of the group.

Quote (⇨ Japanese):An emperor that governs over the central lands, it rules over the Four Holy Beasts that protect the Digital World. Its body is covered in scales made of Huanglong Ore, which is the origin of Chrome Digizoid, thus making it impossible for a scratch to be landed on it.
